Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- the test item is not an irritant to eyes
- Executive summary:
0.1 g of the test substance was administered into the conjunctival sac of in each case one rabbit eye of 3 females and after 24 h the treated eyes were rinsed with physiologic saline.
Evaluation of eye irritation was made according to Draize.
According to the classification criteria Oxaphthalimid is not irritating to eyes.
